4.5 Altitude Setup
Move the highlight over this menu item and press the rotary button to return to the main menu.
Select if you want your altitude readout in feet (ft) or meters (m).
Select if you want your local pressure readout in millibars (mB) or inches of Mercury (“Hg).
Select whether you want the altitude display on the top or on the bottom of the main display.
4.6 Airspeed Setup
All the airspeed parameters can be setup here.
Move the highlight over the “DONE” menu item and press the rotary button to return to the main
menu.
This setup allows your instrument to measure the zero airspeed reading of the
airspeed sensor and set a calibration value internally for this. This is equivalent
to some mechanical airspeed indicators that have an adjustment to set the
needle to zero when the aircraft is not moving. You would use this function
occasionally if you see an airspeed reading when the aircraft is at rest. This
may be caused by aging of the built in pressure sensor or related electronics. When you perform this function, make sure
that no wind is blowing into the pitot tube as this would result in an incorrect internal calibration.
Pressing the F1 key will zero the airspeed sensor.
Enter whether you want the airspeed to display true airspeed (TAS) or indicated airspeed (IAS).
Please see section 6 below for more information on true airspeed (TAS).
